New Training Topics Coming Soon

At Kruse Training we pride ourselves on the ability to consistently add new content and topics that meet the needs of the injection molding industry. With this in mind, we are currently undertaking a series of new topics focusing on areas that move beyond the basics of injection molding to the more complex aspects of…
Torsten’s Training Tip: Cold Runner Types and Designs

Cold runner systems are an important aspect of mold design. By optimizing cold runner shapes and sizes, important molding processes such as pressure drops, polymer shearing, packing and cooling behavior, gate sealing time, and overall cycle time can be made more efficient. Cold runners are simply unheated channels that transport molten polymer material from a…
Torsten’s Training Tip: Sink Marks and Voids

Two common and related injection molding defects, sink marks and voids, are the result of excessive polymer material shrinkage. Because it is essential to produce high quality parts free of molding defects, understanding the causes in order to reduce or eliminate sink marks in molded parts can be very helpful. Let’s review some basics. A…
Torsten’s Training Tip: Gate Seal Time

Gate seal time is an important aspect of the packing phase that needs to be understood to produce high quality molded parts. Setting proper gate seal time plays a key role in packing parts. Properly packed parts will have even internal polymer molecular structure, fewer volumetric shrinkage differences, optimized part dimensions, and fewer sink marks…
Torsten’s Training Tip: Thermal Pins

Designing thermally optimized molds becomes more challenging as part designs become more complex. There are various cooling design strategies, from using drilled coolant circuits or baffles and bubblers, to selecting mold steels or thermal pins (sometimes called heat pipes or heat tubes.) Thermal pins are a cooling strategy to optimize thermal behavior inside a mold.…
Industry 4.0 Meets Learning 4.0

We don’t want to just revolutionize the training industry; we want “evolutionize” your way of learning. Everyone has heard the maxim “time is money” and nowhere is that truer than with training. Consider the time your employees are attending off-site or on-site training, away from their desks or the molding floor, and not productive in…
Torsten’s Training Tips: Understanding Shrinkage and Warpage Behaviors

Minimizing volumetric shrinkages and reducing part warpage are important considerations when designing injection molded parts. By understanding the interaction of part and mold designs, polymer material, and the molding process, preventative measures can be designed into the molding system to minimize shrinkage and warpage. Polymer materials naturally expand when they are heated and shrink as…
New Processing Lessons: Cooling and Packing

We are excited to announce our latest lessons in the Processing category. There are six brand new lessons focused on the Cooling and Packing phase. These lessons continue to build on our foundational level of injection molding training. Filling Phase Lessons Include: Lesson 1 – Packing Pressure Profiles: Amorphous Materials This lesson reviews the internal…
Moldex3D and Kruse Training Collaboration

This week Moldex3D announced their collaboration with Kruse Analysis on the Kruse Training program. Kruse Training lessons contain actual molding simulations that reinforce each lesson’s topic. The visually engaging animations are created using Moldex3D simulation software and provide trainees an opportunity to easily learn and understand basic-to-advanced plastics engineering knowledge and techniques. The goal of…
NPE 2018 Recap and Other News

Almost a month has passed since NPE 2018 ended and aside from catching up on “regular” work (which luckily never ends!), we’ve also been spending time connecting with people we met at the show and integrating all of the great feedback we received into our programs. Watch our recap video to see what we were…
